Musnad al-Humaydi

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates the statement of Sayyiduna Sa'b bin Jaththamah (may Allah be pleased with him): I presented the meat of a wild ass (nilgai) to the Prophet Muhammad (peace and blessings be upon him). At that time, the Prophet (peace and blessings be upon him) was at the place of "Abwa" or perhaps "Waddan." The Prophet (peace and blessings be upon him) returned it to me. When the Prophet (peace and blessings be upon him) saw signs of displeasure on my face, he said: "We did not return it to you because of any dislike, but because we are in the state of ihram."

Imam Humaydi (may Allah have mercy on him) states: Sufyan would sometimes combine both narrations and relate them as a single hadith, and sometimes he would narrate them separately. At first, Sufyan would only narrate the words "wild ass (nilgai)," but later he began to narrate the words "the meat of a wild ass (nilgai)."
